Patented Sept. 12, 1933 UNIT D STATES LIQUID AND SEMILIQUID CONTAINER John Bertram Booth, Croydon Park, New South Wales, Australia Application September 28, 1931, Serial No. 565,504, and in Australia June 5, 1 931 Claims.

This invention relates to containers for liquids, pastes, creams, salves, and other liquid, semiliquid or plastic material from which small quantities of the material may be extracted as desired, and includes means whereby the container may be re-filled without exposing the material to the atmosphere.

In the accompanying drawing which illustrates one form of the invention:

Fig. 1 is a side elevation of a container;

Fig. 2 is a sectional elevation of the same;

Fig. 3 is a similar view of a re-fill carrier.

Each container comprises a casing enclosed V in a slidable sheath 11 and a carton 12 housed in the casing.

The casing 10, permanently closed at its lower end and open at its upper end, is enclosed in the open ended longitudinally slidable sheath 11 which is slightly longer than the casing and, by

the formation of a bead 13 on the upp end of the casing and of an inturned lip 14 on the lower end of the sheath, is non-detachable from the casing.

The upper end of the sheath is fitted with a detachable cover plate 15 to which is secured,

about a central aperture in the plate, a depending tube 16 shorter than the sheath and of any desired internal bore. Near the lower end of I the tube is fitted a collar 17. An externally threaded nipple 18, formed on the plate 15 about the central aperture therein, carries a detachable closing cap 19.

The carton 12 to be housed in the casing 10 is of the same length as the internal length of the casing 10 and is of uniform internal bore. It contains the desired liquid or plastic material, is permanently closed at its lower end, and is closed at its upper end by means of a slidable cork or plug 20 provided with a central aperture 4 21 which is adapted to receive the lower end of the tube 16. The aperture 21 is sealed by means of a tearable disc 22 of paper or the like.

In use, the cover plate 15 having been removed, a filled and sealed carton 12 is slipped into the casing 10, the sheath is slid outwards along the casing to the full extent of its travel, and the cover plate 15 replaced with the cap 19 removed. The sheath is forced inwards and the lower end of the tube 16, if not already in the aperture 21, is pressed through the seal 22 and enters the aperture in the plug until stopped by the collar 17. On further inward movement of moved outwards over the casing the plug 20 rel: mains in its inward position in contact with the material in the carton.

A fresh, sealed carton 12 (Fig. 3) is substituted as a re-fill when the carton in the casing is emptied.

I claim:

1. A container for material of the kind described comprising in combination a casing closed at its lower end, a non-detachable sheath .65 slidable longitudinally over the casing, an apertured cover plate detachably mounted on the upper end of the sheath, a tube depending centrally from the cover plate, a carton of uniform internal bore permanently closed at its lower end and housed in the casing, and a slidable closing plug for the carton adapted to receive the lower end of the tube.

2.. A container for material of the kind described comprising in combination a casing closed at its lower end, a sheath slidable longitudinally over the casing, a cover plate detachably mounted on the upper end of the sheath, a central aperture in the cover plate, a tube mounted about said central aperture and dependingfrom the cover plate, a nipple projecting upwards from the plate in line with the tube, a carton of uniform internal bore permanently closed at its lower end and housed in the casing, a slidable closing plug for the carton, a central aperturein the plug adapted to receive the lower end of the tube, and a tearable seal on the plug about the aperture whereby the tube will break the seal and enter the carton when the cover plate is placed on the sheath. 0

3. A container and dispenser for semi-liquid substances which comprises a carton for containing the substance, a plug having an aperture therein in one end of the carton and slidable therethrough to dispense the substance, a sheath slidable over said carton, a tube extending through said sheath and having an end in alignment with and slidable into said aperture.

4. A container and dispenser for semi-liquid substances which com prises a carton, for containing the substance, a plug having an aperture therein in one end of the carton and slidable therethrough to dispense the substance, a tearable seal covering said aperture, a sheath slidable over said carton, a tube extending through the sheath in alignment with said aperture whereby it will pierce said tearable seal and enter the aperture upon sliding movement of the sheath.

5. A container and dispenser for semi-liquid substances which comprises a carton for 'conture whereby it will pierce said tearable seal and enter the aperture upon sliding movement of the sheath, and a collar on said tube to abut with said plug and force it through the carton.
